Abstract
The utility model discloses a complete welding ball valve with a wedge-type multi-seal welding valve neck, which is suitable for pipeline controlling and mainly applied in oil and gas pipeline cutting and stations of valve rooms, and belongs to the technical field of valves. The complete welding ball valve has the key points of adopting a structure of a wedge-type multi-seal valve neck seal and integrated full welding valve neck. The valve neck is provided with a multi-seal structure of wedge-type graphite seal and O-shaped rubber ring seal, therefore, absolutely reliable self-seal and fire-proof functions can be achieved under the pressure of a medium. Furthermore, with the adoption of the integrated full welding valve neck, no connecting seal surface of bolting and sectional type valve necks is available, thereby completely preventing the possibility of the leakage at the valve neck, and greatly improving the intensity and rigidity of the valve in the operating process.
Description
Affiliated technical field
The utility model relates to universal machine valve technology, belongs to the improvement of welding ball valve structure.It is used for long-distance transport pipes, plays a kind of medium of opening or close, and especially can be used as the main line ball valve of every performance requirement strictness.
Background technique
Existing full soldered ball valve mainly is made up of valve body, side valve body, spheroid, valve rod, valve component, bearing block assembly, common bolt gland or segmented welding gland, seal ring, tie-plate etc.Its valve neck structure has two kinds: a kind of is that its valve neck is the fixing gland structure design of socket head screw, and the stuffing box packing between its gland and the valve rod is that precompression is installed, and does not have the stuffing box packing of Compensation Design.Another kind is that its valve neck is the fixing upper and lower segmented gland structure design of socket head screw, lower cover and valve body welding, and the logical bolt of upper press cover is connected with lower cover.Stuffing box packing between its lower cover and the valve rod is still installed for precompression, does not also have the stuffing box packing of Compensation Design.The influence that these two kinds of structures all can be rotated the abrasive action that forms owing to the compression accuracy and the valve rod of filler, its sealability is difficult to be guaranteed; After valve was installed to the field or installs with burying, rainwater or underground water also were dipped in the screw hole by upper and lower two faying surfaces of gland or upper press cover in addition, and double thread and inner sealing produce action of rust, constitute potential safety hazard.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, and a kind of sealing effect that can effectively improve between gland and the valve rod is provided; Can avoid again soaking corrosion to connecting thread and valve neck inside thereof; Can also reduce the mating face, reduce producing the full soldered ball valve of many seal weldings of wedging type valve neck that leaks possibility.
The purpose of this utility model realizes by following technical measures: the full soldered ball valve of this many seal weldings of wedging type valve neck includes valve body, side valve body, valve rod, spheroid, valve seat, valve seat supporting, thrust bearing, bearing support, sliding bearing, axle sleeve, gland, tie-plate, and its innovation part is at first that gland and valve body is integrally welded.It two is provided with the O-ring seals that is no less than three roads on the inner hole wall of axle sleeve, also be provided with the O-ring seals that is no less than three roads on the cylindrical of axle sleeve.Its three sealing configuration that also ring, wedge type self-tightening filler outer shroud and packing press ring are formed in the upper-end surface of axle sleeve is provided with by wedge type self-tightening filler with automatic compensating action.It four also is provided with the snap ring with built-in seal action in the upper oral part of gland.Also the applying end face of gland and tie-plate is provided with the O-ring seals that is no less than twice at last.
The utility model beneficial effect compared with prior art is to have realized the automatic compensation that seals between valve rod and the gland reliably, and its sealability greatly improves.Avoided the corrosion of immersion effectively to connecting thread and gland inside thereof.Junction plane between part reduces, and has reduced the possibility that this valve leaks, and has improved intensity and rigidity in the valve operation process simultaneously.
Description of drawings
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
The figure number explanation:
1, tie-plate 2, socket head screw 3, gland 4, thrust bearing 5, valve rod 6, O-ring seals 7, valve body 8, O-ring seals 9, ring 10 in the wedge shape self-tightening filler, wedge type self-tightening filler outer shroud 11, packing press ring 12, snap ring 13, O-ring seals 14, O-ring seals 15, locating stud 16, O-ring seals 17, axle sleeve 18, hanger 19, grease pouring valve 20, safety check 21, locating stud 22, spheroid 23, valve seat supporting 24, O-ring seals 25, valve seat 26, spring 27, bearing support 28, foot rest 29, thrust bearing 30, blowdown plug 31, sliding bearing 32, the side valve body
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: the full soldered ball valve of this many seal weldings of wedging type valve neck is mainly by valve body 7, side valve body 32, valve rod 5, spheroid 22, tie-plate 1, gland 3, axle sleeve 17, and compositions such as valve component, bearing block assembly and Sealing.Wherein the gland 3 of this ball valve is not bolt with being connected of valve body 7, neither segmented welding, but with whole gland 3 directly and valve body 7 integrally welded.And on the inwall of axle sleeve 17, set gradually three road O-ring seals 6, on the cylindrical of axle sleeve 17, also set gradually three road O-ring seals 8 simultaneously.The sealing configuration of also in the upper-end surface of bearing 17 is provided with by wedge type self-tightening filler, encircle 9 in addition, wedge type self-tightening filler outer shroud 10 and packing press ring 11 being formed with automatic compensating action.Also in the upper oral part of gland 3, be provided with snap ring 12 with built-in effect.After being installed to the field or installing with burying for fear of this ball valve, rainwater or the stratum water faying surface by gland 3 and tie-plate 1 is to the erosion of internal structure, and also the applying end of gland 3 and tie-plate 1 is provided with O-ring seals 16 and O-ring seals 14 at last.The structure at this other position of ball valve and existing ball valve are basic identical.
